Be it known that we, CHARLES H. PALMER and JOHN W. DENMEAD, of Akron, inthe county of Summit, and in the State of Ohio, have invented certainnew and useful Improvements in Box-Making Machines, and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, in whichFigure 1 is a top plan view of a machine embodying our invention, formaking box shucks or slides.

Letters of like name and kind refer to like parts in each of thefigures.

The object of our invention is to provide a machine for making shucks orslides for match and other boxes capable of rapid work and the making ofa perfect product, and to this end, said invention consists in themachine having the features of construction substantially as hereinafterspecified and claimed.

Our invention belongs to the type of box making machines in which isemployed stock that is fed to the machine in the form of a continuousstrip of paper which is thereby folded into a tube, and cut into desiredlengths, and, in the embodiment of our invention which we have chosenfor illustration, we provide a frame or bed A, supported by legs a anda, above and parallel with which frame is supported a long, horizontalbar B that constitutes a mandrel or former upon and about which thestrip of paper is folded to form a tube of a form agreeing in crosssection with the cross section of the mandrel The paper strip is takenfrom a roll, conveniently placed, being passed first over aglue-applying device to receive along one edge of the strip, theadhesive required to join the two edges when overlapped, said devicecomprising a narrow-faced wheel F that takes liquid glue from a suitablepot, and mounted on a shaft D journaled in bearings in plates E and Ebolted to the frame A. Upon the shaft D is a second wheel C placed toengage and support the strip of stock at or near its opposite edge. Thestrip is next passed to and around a roller G supported by a pair ofarms or bars II and H that are attached to and project from the end ofthe frame A, the strip being thereby reversed, so as to bring itssurface with the glue, uppermost, and from thence it passes between apair of feeding and scoring rolls I and I, placed one above the other,in bearings in the plates E and E, and being respectively provided withcircumferential grooves and ribs for scoring the strip at the pointswhere it is to bend in being folded. Power is applied to the lowerscoring and feeding roll I by the means hereinafter described, the tworolls being geared together by gear wheels K and K, and, preferably, theglue wheel is driven from the lower roll I by means of a gear wheel L onthe latter that meshes with a gear wheel M on the glue wheel shaft D.The strip is held from displacement in a sidewise direction by means ofsmall rollers N and N supported by a bar in advance of the rolls I andI. Projecting from the upper roll I nearest the side of the strip notsupplied with glue, is a radial pin or stud i and in line therewith, inthe under roll I, is an annular groove 2". The function of the pin 2' isto assist in registering the paper from which the boxes are made, thepaper being previously printed and perforated along one edge at properpoints and intervals, said pin entering the perforations in the paperand thus imparting to the paper a uniform movement as it feeds throughthe machine. This prevents the paper either gaining or losing, and pre.

serves an accurate register so that the proper printed matter willappear on each completed box.

From the rolls I and I, the strip is passed beneath the mandrel B, anend of which is supported a short distance from the rolls, by means of abracket 0 bolted to the frame A, that arches over the mandrel, a bolt Pbeing passed through the bracket into the top of the mandrel. A bar Qbridges the space between the rolls and the end of the mandrel tosupport the strip, and it is prolonged beneath and parallel with themandrel to support the strip and prevent it sagging. Preferably, theportion of strip be tween the rolls I and I and the end of the mandrel,is formed into a bight or loop. The purpose of forming this bight orloop in the strip is to enable the glue to set, this being obvious fromthe fact that the bight or loop provides a point, in the travel of thepaper strip through the machine, where the moist glue will be exposedfor a short time to the air, thereby permitting the same to set, asstated. The bight or loop also assists in the feeding of the strip bythe feeding rolls, the strip being thereby freed from longitudinaltension, and consequently each pair of feeding rolls will act upon thestrip ithout afiecting the other pair.

At a point about mid-length of the mandrel, on each side thereof, is aroller R which supported by an arch-form bracket S bolted to the frameA, the roller axis being inclinedso that its upper end is toward thereceiving end of the mandrel and its lower end toward the box-deliveringend thereof. The paper strip, being partially folded up toward the sidesof the mandrel, is passed between the latter and said rollers and thuspressed against the sides of the mandrel, and by reason of the describedinclination of the rollers is subjected to a lifting action that tightlydraws the strip to make it conform to the bottom and sides of themandrel. To resist the upward strain to which the man drel is thussubjected, there is a bolt or screw T passed through the top of the archS, which bears at its lower end against the top of the mandrel.

At a point beyond the rollers R and R, above the mandrel, is fixed afolder plate U of such shape that it will engage and fold down upon themandrel top the unglued edge of the strip, the other glued edge beingnext engaged and folded down upon the former by ahorizontal flange '2)on the upper end of one of two rolls V and V placed, respectively, onopposite sides of the mandrel, being fined upon vertical shafts W andlV, journaled in boxes in a frame X bolted to the frame A and archingthe mandrel. The flange o of the roller V is of such diameter that itreaches across the top of the mandrel, and acts to iron or firmly pressthe two lapped edges of the strip together, while the sides thereof arepressed by the two rolls V and V and the bottom is pressed by a flange aon the lower end of the roll which has the flange o, so that afterpassing the rolls, the strip is transformed into a closed-sided tubethat curately conforms to the cross section of the mandrel, and is readyto be cut into lengths to form perfect shucks ready for immediate use.The sides of the strip are keptclose to the mandrel against any outwardtendency caused by the pressure applied to the two ec ges, by means of astrip or finger Y projecting alongside of the mandrel, and fastened toand supported by the frame X. The folder plate U is also at tached toand supported by the frame X.

Beneath the mandrel, on a shaft Z journaled in bearings in brackets Aand A on the frame A, is a feed wheel B which projects through a slot inthe paper supporting bar Q so that its periphery can engage the paper onthe underside of the mandrel with sufficient friction to feed it along.The means for driving the feed wheel shaft will be presently described.The mandrel is also supported against upward pressure at this point bythe device S previously mentioned.

The two roll shafts .V and \V, are geared together by intermeshingwheels w and w on the upper ends thereof, and on the lower end of one ofsaid shafts is a bevel pinion w meshing with a bevel gear wheel "0' upona shaft D journaled in hearings in the frame A. Upon one end of saidshaft D is fixed a ratchet wheel E with which a pawl f on a disk F,loose on the shaft D, coeperates to impart to the rolls V and V anintermittent motion. Power is taken from the shaft D to drive the feedwheel shaft Z by means of intermeshing wheels G and H on the respectiveshafts.

The pawl-carrying disk F is oscillated by being connected by a pitman lwith a crank disk K upon a shaft L mounted in bearings in the frame A,and provided with a driving .pulley M.

For driving the feeding and scoring rolls I and T and the glue wheel inunison with the rolls V and V and the feed wheel B, there is provided onthe shaft of the lower roll I a pawl and ratchet mechanism similar tothat on the shaft D, the pawlcarrying disk K of which is connected tothe disk F by means of a rod or bar, 0.

.Bolted to the side of the roll-supporting frame X is a bracket P havingan opening through which the mandrel extends, and having on each side ofthe latter, a hori- Zontal guideway in which is mounted a slide Q to theouter face of which is attached a knife comprising a vertical blade 9and up per and lower horizontal blades g and g which project beyond thevertical blade. Each knife is adapted to cut one side and at least halfthe top and bottom of the paper tube on the mandrel, and for proper cooperation with the knives, the mandrel is recessed or cut away on eachside to permit the knives to pass through the tube walls. The edge ofthe recess past which the knives move is parallel with the plane ofmovement of the knives, and the mandrel adjacent to such edge is coveredwith a hard ened shell R that can be replaced when necessary because ofwear. Connected to the center of each knife-carrying slide Q, is alongitudinally-extending tension rod Q which rods pass through atransverse guide bar Q arranged at the rear side of the bracket X, thefree ends of said rods being encircled by coiled springs S which bearagainst said guide bar and exert their tension to normally draw the rodsQ rearwardly. Thus said rods draw and hold the knife-carrying slides Qagainst the back of the knife guide, which action automatically takes upwear and maintains the knife in position for always performing clean,accurate work.

The knife-carrying slides Q, and Q are reciprocated by levers T and Tpivoted to the bracket P, whose upper ends are respectively connected tothe slides, a cam U on the shaft L acting on each lever to move it inone direction and a spring V moving it in the opposite direction. Thetwo cams U and U are so timed that, in cutting, one knife is movedslightly in advance of the* other, so that neither will interfere withthe other. The shuck, which is formed by being cut from the tube, ispassed along and off the mandrel ready for immediate use, if it is notto be used for match boxes that require to be sanded.

It will be understood that in the beginning of the operation of themachine, the paper is placed on the mandrel by hand, but thereafter, thework of forming the tube and cutting it into shuck lengths is carried onautomatically.
